I have a quick question that has been on my mind for a while : let's say that in my Python code, I have a large array which represents the raw results of a MCMC run. Then, after importing the GetDist module, I create a "MCSamples" object based on this array.

Now if I run these two lines of code :
> g = getdist.plots.getPlotter()
> g.triangle_plot(MC,names)
I was wondering if there was any kind of processing (for example some form of automatic thinning maybe) that was done on the chain by GetDist before it plots the corresponding histograms and 2D contours ?
